8 MultiModemISI Hybrid Series, ISIHI-2S/2U

Chapter 1—Introduction

Modem Description/Features

ISIHI-2S/2U modems include an Intel 20 MHz 80186 processor and 254K of RAM that

work dynamically to allocate resources to the most active modems.

Simple to install, the ISIHI-2S/2U can be used to add multiport, Enhanced V.34 modem

communications to a network host or server as easily as plugging in an expansion card,

loading the driver software, and connecting the phone lines.

The ISIHI-2S/2U contains four modems, which meet the proposed Enhanced V.34 ITU

standard for data signalling rates as high as 33.6/31.2 Kbps full-duplex mode. They

support and are compatible with EIA extended Automode, adaptive line probing,

automatic symbol rate and carrier frequency during startup, and retrain and rate

renegotiation (in 2400 bps increments.)

The ISIHI-2S/2U features CCITT V.42 error correction and V.42bis data compression,

providing 100% error-free data transmission. V.42 error correction incorporates MNP

Classes 3 and 4 and LAP-M. You can select V.42bis data compression for 4-1 throughput

or MNP Class 5 for 2-1 throughput.

ISIHI-2S/2U modems offer interactive automatic dialing as well as Command Mode

option configuration. You can store up to ten command line/telephone numbers (up to 60

characters each) in the ISIHI-2S/2Us nonvolatile memory.

ISIHI-2S/2U modems offer pulse or tone dialing and recognize dial tones and busy

signals for reliable call-progress detection. They detect AT&T calling card tones and are

FCC-registered for connecting to telephone networks without Data Access Arrangements

(DAAs).

They also feature Remote Configuration, which allows you to assist users at remote sites,

saving you the time and trouble of site visits and preventing misinterpretation of

configuration instructions.

The ISIHI-2S/2U meets the CCITT V.17 standard for sending and receiving faxes. When

lined to a compatible fax machine or modem, ISIHI-2S/2U modems can transmit faxes at

14.4 Kbps. They meet the CCITTs Group 3 Designation for sending and receiving faxes

at 9600 bps and Group 2 Designation for sending and receiving faxes at 1800 bps. The

ISIHI-2S/2U also is downward-compatible to speeds as low as 300 bps, so you can send

and receive faxes with virtually any fax machine in the world.
